Valve body manufacturing method

Abstract

A method for manufacturing a valve body, comprising the following steps: 1) Melting copper in a closed environment, adding carbon and mixing them thoroughly; 2) injecting the material in step 1 into a mold cavity under pressure to form a "convex" shape Valve body; 3) Slowly cool down the workpiece in step 2 and take it out; 4) Electroplate the workpiece in step 3; 5) Grind the inner wall of the workpiece in step 4; 6) Turn both ends of the workpiece in step 5 out thread. The invention adopts the method of adding carbon to improve the wear resistance of the inner surface of the valve body, slow down the corrosion of the copper valve body, and avoid the generation of the original battery effect.

Description

technical field [0001] The invention relates to a method for manufacturing a valve body. Background technique [0002] As we all know, copper valves are prone to rust and produce patina. In order to ensure the shelf life of copper, copper is mixed with alloys to prevent rust. However, alloy metals are prone to galvanic effect and accelerate corrosion. Contents of the invention [0003] In order to overcome the disadvantages that the existing copper valve body is easy to rust and the alloy is easy to produce galvanic effect, the invention provides a manufacturing method of the valve body. [0004] The technical solution for solving the technical problem of the present invention is: a valve body manufacturing method, comprising the following steps: [0005] 1) Melt the copper in a closed environment and mix it with carbon, and make it fully mixed; [0006] 2) Inject the material in step 1 into the cavity under pressure to form a "convex" valve body; [0007] 3) Slowly co...
